Question

In the given figure, the value of x is
(1) 35°
(2) 45°
(3) 50°
(4) 60° ​

Answer 1

Answer:

(4) 60° ​

Step-by-step explanation:

we know that sum of any two interior angles is equal to the opposite external angle.

so 3y + x = 7y

so x = 4y

therefore 4y + 3y + 5y = 180

12y = 180

y = 15

so x = 4y =(4) 60° ​

4*15 = 60°
